Question

in a scientific investigation, the term \quantitative data\ refers to numbers that are usually followed by photos of measurement. written descriptions. graphs. units.

Explanation:

Quantitative data in scientific investigations involves numerical values. These numbers are typically associated with units (e.g., 5 meters, 10 grams), as measurements have units to define what is being measured. Photos of measurement are not numerical data, written descriptions are qualitative, and graphs are a way to represent data, not what follows the numbers in quantitative data.

Answer:

units.
